IBH--I have Lyme Disease and have had it twice in the past. We've also had 3 dogs that have contracted it. We spend a lot of time in the woods, and deer ticks are all over the place.
I assume that you're on a regimen of doxycycline or amoxicillin. Although doctors often suggest only a two week period of meds, I think 3 or 4 weeks is best. Did you have the bulls-eye mark at the site of the tick bite?
Actually, the doxycycline works wonders for me. My main symptoms involve a very, very stiff neck, but the doxycycline does the trick for me. Also, when you're in the woods try to use an insect spray with Deet.
I don't think I have any memory loss, but then it's all kind of vague...... :-)
Good luck.
